This is not a dish to prepare if you've got a papercut. Screwing around with ancho chili powder, chipotle peppers, lime juice, and adobo sauce with even a mild flesh wound will be a painful experience that you'll not soon want to repeat. Bust out the rubber gloves if necessary—you're going to need your stamina when you start chowing down on these insanely spicy grilled wings.
But... wow! These are great! Perhaps not best suited as a main course (you need a lot of them to fill you up), but as an easy prelude to some other grilled delight, they're damn near perfect. I'd say they're even worth the humiliation involved with buying one of those giant packages of supermarket wings, which can usually be had for around a dollar a pound.
If you've got a gas grill (as I do), do some quick research on the subject of indirect heat. If you're unsure of yourself, keep the flame on the low side, since you can always bump it up later on if you feel like they're not cooking through. Remember, dark meat is very forgiving on the grill—it takes real talent to terminally ruin it, so keep that in mind as you dial up your burners in search of the sweet spot. These wings go brilliantly with harvest grains, grilled veg of your choice, and a tall glass of hard cider. Don't forget the cilantro!
